Mixtures can either be homogeneous or heterogeneous. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present.One example of a mixture is air. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures.A homogeneous mixture in which there is both a solute and solvent present is also a solution.ir is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.

Why does it glow blue? It's the Cherenkov radiation: 'Cherenkov radiation is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium at a speed greater than the phase velocity of light in that medium.' It's going faster than the speed of light (in water).
A bizarre natural phenomenon lights up the water off these three beaches, making the sea shine with a surreal blue light. As night falls on certain beaches around the world, the waves glow with an eerie blue light: tiny, neon dots that make it look as though stars are washing up on shore. The surreal scene arises not from magic, but from plankton that have evolved to glow in order to startle or distract fish and other potential predators.
